NickelCobalt
Overview
Miitel Mine, operated by Mincor Resources, is an underground nickel mine located in the Kambalda District of Western Australia, Australia. The mine is situated on the eastern side of the Widgiemooltha Dome, approximately 55 kilometres by road southwest of Kambalda.
Production
From March 2001 to June 2004, the mine produced 697,000 tonnes of ore at a grade of 3.95% nickel. By 2010, the mine had produced nearly 55,000 tonnes of nickel-in-ore since it began production in 2001. In 2015, concentrate produced from the Miitel and Mariners mines contained 96 tonnes of cobalt.
Processing
no specific on-site processing plant at Miitel. The extracted ore is hauled to BHP's Kambalda Nickel Concentrator for processing under an Ore Tolling and Concentrate Purchase Agreement.
Expansion
A 2020 Definitive Feasibility Study for Mincor's Kambalda Nickel Operations outlined a plan to restart the Miitel mine, contributing in the back half of a five-year project life. This plan involved dewatering and rehabilitating the mine for the extraction of the South Miitel and Burnett deposits.
